CONTAINER, CONTAINER WITH STORED OBJECT, PRODUCTION METHOD THEREOF, THAWING METHOD, AND PRODUCTION METHOD OF CELL PREPARATION

To provide a container with a stored object, a production method thereof, a thawing method and a production method of cell preparation.SOLUTION: There is provided a container 10 for storing a biological substance, comprising: a cylindrical container body 20 having a first end 23 and a second end 24, in which at least the first end is closed; and an extended part 40 coupled to a coupling part of the container body. The container body comprises, in a direction where the container body extends, a storage part 21 which is provided closer to the first end side relative to the coupling part and stores therein a stored object. In a cross section of the container passing the coupling part and being vertical to a direction where the container body extends, a possible minimum value of a distance between a first tangent line of the container contacting a contour of the container and a second tangent line of the container contacting the contour of the container and being parallel to the first tangent line of the container is greater than a possible minimum value of a distance between a first tangent line of the container body contacting the contour of the container body and a second tangent line of the container body contacting the contour of the container body and being parallel to the first tangent of the container body.SELECTED DRAWING: Figure 1 【課題】収容物入り容器、収容物入り容器の製造方法、解凍方法および細胞製剤の製造方法の提供。【解決手段】生体物質を収容する容器10であって、第１端部23と第２端部24とを有し、少なくとも前記第１端部が閉鎖されている筒状の容器本体20と、前記容器本体の接続部に接続した広がり部40と、を備え、前記容器本体は、前記容器本体の延びる方向において、前記接続部よりも前記第１端部側に位置し、内部に収容物を収容する、収容部21を有し、前記容器の、前記接続部を通り且つ前記容器本体の延びる方向に垂直な断面において、前記容器の輪郭に接する容器第１接線と、前記容器の輪郭に接し且つ前記容器第１接線に平行な容器第２接線と、の距離がとり得る最小値は、前記容器本体の輪郭に接する容器本体第１接線と、前記容器本体の輪郭に接し且つ前記容器本体第１接線に平行な容器本体第２接線と、の距離がとり得る最小値よりも大きい、容器。【選択図】図１
